CLOSURE CAP.

Application filed September 24, 1926. Serial No. 137,543.

The present invention relatesto a closure cap, being more especiallyadapted foruse on milk bottles, or the like, and aims to provide a noveland improved cap of this character which can be conveniently andefiiciently removed from a bottle, or like container, without danger ofspilling the contents in the container.

Another object of the invention is to provide a closure cap constructedfrom one piece of relatively thin cardboard or similar material, havingthe marginal edge thereof turned over and pressed down on the body ofthe cap to reinforce the same at the periphery thereof and to providefinger engaging portions for removing the cap from the bottle, or likecontainer.

It is also an object of the invention to provide a cap of the aboveindicated character, which is extremely simple and substantial inconstruction, which can be manufactured economically, and which will bethoroughly efiicient and practical in use.

With the foregoing and other objects in F View, which will be apparentas the description proceeds, the invention resides in the constructionand arrangement of parts, as hereinafter described and clalmed, it beingunderstood that changes can be made within the scope of what is claimed,without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a top plan of my improved cap, 7

Figure 2 is a cross section taken on line 22 of Figure 1, and

Figure 3 is a view similar to Figure 2, showing the cap arranged forclosing the mouth of a milk bottle.

In carrying out my invention, the numeral 10 designates a piece ofcardboard which is relatively thin. The piece of cardboard when cut orstamped out is of circular formation and has the marginal edge thereofturned over and pressed down in close contact with the body of the cap,as at 11. When turning the marginal edge of the cardboard over andpressing the same down, pleats 12 are provided. The pleats extendinwardly of the cap approximately onesixth of the diameter thereof,which will reinforce the relatively thin cardboard at the periphery ofthe cap so that the periphery of the capwill snugly engage a bottle orllke closure when arranged thereon. The marginal edge of the blank pieceof cardboard from which the caps are constructed 1S turned over the samedistance from the edge of the cap entirely around the same so that saidturned over portion extends inwardly toward the center of the cap a likedistance entirely around same.

The purpose of turning over the edge of v the cap is not only forreinforcing the same at the point where the cap contacts with the neckof a bottle, or like container, but is also for the purpose of providingfinger engaging portions in order that the cap may be easil' andefficiently removed from a bottle, or 11 e container, without danger ofsplashing or spilling the contents in the bottle,

or like container.

By constructing my improved cap in this manner, it is to be noted thatcaps can be constructed from material relatively thinner than that nowcommonly used, as the turnlng over of the edge of the cap will reinforcethe same and provide sufficient friction at the neck of the bottle, orlike container. Caps are commonly sold according to weight. Thus theWeight of one of my improved caps would be approximately one-quarterless the weight than caps now used.

-When it is desired to remove oneof my improved caps from the neck of amilk bottle, or like container, the person removing the cap engages oneof the pleated portions of the turned over portion 11 between the indexfinger and the thumb of one of his hands so as to obtain sufiicientgripping thereof in order to overcome frictional engagement of the capwith the bottle. By then pulling on the turned over portion, the cap maybe easily and eificiently removed. It is to be noted that the pointwhere the turned over portions are provided is at the point where thecap engages the bottle, and at a point where the contents of the bottlehardly contacts with the cap to moisten the same and loosen the fibersin the cardboard, which would tend to permit easy tearing or pullingofthe finger engaging portion from the body of the cap. Furthermore, all

of the pleats are attached together so that pull upon one of said pleatswill be transmitted to the pleats adjacent thereto, thus alsoeliminating the tendency oi the pleat being engaged from being torn fromthe body of the cap during removal of the cap.

Having thus described my invention, what I claim as new is:

1. A closure cap constructed of one piece of sheet material of circularformation and having the portion adjacent the periphery thereof turnedover on the body portion so as to increase the thickness of said cap atthe horizontal circular marginal edge thereof.

' 2. A closure cap contructed of sheet matepleats forming fingerengaging portions for I removing the cap.

3. A closure cap constructed of one piece of material and having themarginal edge turned over on itself and pleated for reinforcing themarginal edge of the cap that engages the cap groove of a bottle.

In testimony whereof, I have afiixed my signature.
